It marks the first time black hole awakening process has been seen as it happens.
WASHINGTON - At the center of the Milky Way galaxy resides a supermassive black hole four million times the mass of our sun called Sagittarius A* that some scientists have called a gentle giant because of its quiescence. But someday it could become a beast.
A light year is the distance light travels in a year, 5.9 trillion miles . Black holes are extraordinarily dense objects with gravity so strong that not even light can escape. The researchers said it appears that a spinning disk of diffuse material has formed around the SDSS1335+0728 supermassive black hole, with some of the matter being consumed.
"These nuclei are characterized by emitting large amounts of energy at a variety of wavelengths, from radio to gamma rays. This galaxy, with a diameter of around 52,000 light years and a mass equivalent to about 10 billion sun-sized stars, had been observed for decades before sudden changes were detected in 2019. The luminosity at the heart of the galaxy has been rising in observations since then.
